I'm in my 70's and received a gift certificate from my daughter-in-law to go to Mark as a trainer. I hadn't exercised for over a year!After only five months with Mark, I feel better and more active than I have in 30 years! I never dreamed I would would swing kettle bells, lunge with a pole in my hands, or do pull-ups and dips, but Mark told me my body could do anything if my mind would let it, and it's true! Thanks, Mark!!
